Thorsten Klein is the creator of k3d, a tool that lets you run a lightweight Kubernetes cluster (k3s) inside a single Docker container. This makes it much easier to spin up a Kubernetes cluster in places like your dev environment, your CI pipeline, or a low-resource environment like a Raspberry Pi.

Thorsten is a DevOps engineer at Trivago, where he works on developer experience for a team that maintains a set of bare-metal Kubernetes clusters. We chat about the ways in which developers are using k3d, Thorsten's motivations and inspirations for writing it, and other tools he finds useful in the Kubernetes ecosystem.
